I had trouble finding the ESP Formula M 5w-40, so I switched to Pentosin HP2 5w-40 as it is listed with MB-Approval for 229.51. When I bought it, it was $37 per 5 Liters at RMEuropean, looks like its $43 for the same jug at Amazon.

 

How many miles/km's for OCI
If were talking premium oils OCI is valid

 

Recently bought new spec Mobil 1 0w30 from O'Rilley Auto Parts for $5.99/qt. They special ordered it from their warehouse stock.

 

Anyone use Rotella T6 Full synthetic?

 

It is not MB rated for DPF vehicles.


Neither is Delvac 1 ESP (even with the ESP designation)

 

So what should we use if we can't get the original anymore?

 

Mobile 1 5w-30 esp or 0w-30 esp Both meet 229.51 approvals
I currently am using 0w-30 esp and so far seems fine

 

I use T6 in my ML, but Mobil 1 in my CDI. T6 got rid of peanut butter.

 

Local Walmart/Autozone/Advance didn't have any ESP mobile 1. Does anyone recommend another place to get it at a fair price? Amazon/eBay seems a little high.

 

Recommend reading previous posts here.

 

Did you try Napa? Even if Napa doesn't have it they should be able to order it for you.
You could also go to mobile 1's site they use to have a store locator and then just call all of them.

 

I went to the dealership today and the specified oil for an 06 E320 CDI is Mobil 1 ESP 0w30. The part number is Q1090182 is the new number that superseded the Mobil 1 ESP 5w40 viscosity. Paid $6.95/Quart, list is $10.50. I too was questioning the parts manager but he double checked and reassured me this is the new oil.

Oil filter part number is 613-180-00-09 paid $9.60, list is $12.00

 

I'll pre-face by saying that I have the om642, not sure if we're all talking about the same engine and how much of a difference it make as to if all the diesels were to take 229.51 spec oil. From the bit of research that I've done, I found a few sources that stated the Mobil 1 ESP 5w-40 is being discontinued. The MB branded bottles is rumored to be Mobil 1 ESP 5w-30. The MB packaged bottles have a green cap and says spec 229.52. I found 2 train of thoughts for the new spec. 1 was that it is to try to address some of the oil leak issues from over the past few years. 2nd was that it is to improve emissions/fuel economy.

I've tried a few oils and haven't noticed any change in performance or fuel economy. Spec 229.51 has 0w-30, 0w-40, 5w-30, & 5w-40 oils. Spec 229.52 is only 0w-30 & 5w-30. I'm under the assumption that my ML came factory filled w/ Mobil 1 ESP 5w-40, which probably also had another additive pkg for break-in. My 1st oil change I used the Amsoil 5w-40. Next one I forgot to order in time for when I planned to do the oil change so I picked up Mobil 1 5w-40 from the dealer when I went to get a filter. For the 3rd change I had happened to be at my BMW dealer and found that they carried the Castrol Professional OE 5w-30 for their diesels. The Castrol carries both BMW LL-04 and MB 229.51 approval and was just under $6/qt w/ my BMWCCA discount. This last oil change is when I found BMW and MB both switched to their own packaged bottles. BMW's repackaged oil for the diesels is a Shell 5w-30 LL-04 oil but I couldn't find exactly which one There's 4 Shell oils that meet their spec and 1 Pennzoil that meets BMW & MB specs. As I mentioned above, I was told MB's repackaged oil is Mobil 1 ESP 5w-30. However, my local Advance Auto Parts store had Valvoline SynPower MST 5w-40 on sale for $5.59/qt which has the MB 229.51 approval so I used that this time around.

229.52 https://bevo.mercedes-benz.com/bevol...229.52_en.html

 

AMSOIL European Car Formula 5W40 is indeed on the MB list of 229.51 approved oils. https://bevo.mercedes-benz.com/bevol...229.51_en.html

 

Looks like AmsOil decided to up there specs.

 

Amsoil had the MB spec on their bottle label back when I was using it 2-3yrs ago in all my cars, hence why I also used it in the MB. I can't comment if it was also on the MB spec sheet as I can't remember. Due to the number of people that seem surprised to see it on the sheet, I'm inclined to believe that it was not.

 

Do you use red label or black label?

 

I am in the surprised camp as well that Amsoil is actually on the list now as I know they claimed it met the specs but never paid to get it tested and actually approved.
I never liked them because some of the sales guys were flat out lying to people but now that they manned up if I can get a good price I would try it.
I am currently trying out the 0w-30.

 

They have two different oils. One is 229.5 and the other is 229.51

 

While we're on the "oil specs" topic, you all may be interested in data and insight posted this week from Ausmbtech in my thread as found here: https://mbworld.org/forums/diesel-fo...-seized-3.html

The OM642 engine in my 2010 ML350 Bluetec seized in April this year @ 82K miles after all regular dealer maintenance. The dealer used MB Part # Q1090143 MOBILE 1 ESP FORMULA MB 5W40 at each and every oil change service, as noted on all of my dealer service invoices. It's becoming more clear to me why 5W40 oil is not to be used in the OM642 and other diesels.

 

Mercedes Benz changed the oil spec and notified the dealer network. They did not make much of an effort to notify the customer.

I would research and carefully before selecting an oil.

229.52 appears to be the only way forward based on the documentation I've researched.

 

My preferred oil for current MB diesels is the new Mobil 1 ESP X1 0w30. It has 229.31, 229.51 and 229.52 approvals so it's easier to have one oil for a range of vehicles.

Non-DPF 646, 647, 611, 612, 613's and earlier engines I still use Regular Mobil 1 0w40 which is a 229.5 oil
